Stand Alone Primary Site and CAS Installatiion !!

I have seen a lot of Posts on Internet which were written on SCCM 2012 and owners have not modified their Posts which is causing a lot of problems for the new admins / architects ?

With SCCM 2012 ( Prior SP1) Release it was not possible to add a CAS after the installation of Stand Alone Primary Server , however with SCCM 2012 SP1 this is very much possible.

 

So you may start with a stand Alone Primary and later on as need be you may add CAS and other Primaries in the hierarchy .
